Recombinant tuna FGF-2 protein 154 aa (bFGF/basic FGF) for the development of optimised serum-free culture media for species-specific yellowfin tuna (Thunnus albacares) in cellular agriculture protocols and veterinary research applications. This longer form of FGF-2 is used in comparative cell culture media optimization studies alongside Qk104, the 145aa form of tuna FGF-2.
FGF-2 is used extensively in the maintenance and proliferation of induced pluripotent (iPSC) and embryonic stem cells (ESC) and for enhancement of proliferation in primary tuna cell culture. Receptor binding affinity and efficacy may differ depending on each species. Using a species-specific growth factor enhances receptor binding affinity, resulting in a lower concentration required in culture.
Tuna FGF-2 is a high purity 17 kDa FGF-2 / bFGF protein, animal origin-free (AOF) and carrier-protein free (CF).
